This leaves just one other offering that Supersprint makes, the NON-stepped 'Tubolare' header. If I had to guess, I would assume that these are either Supersprint Non-stepped headers or a copy.

Some things that stand out to me:
-As Obioban mentioned, the metal used just does not look like the typical steel used by Supersprint. Especially with the corrosion on these on the collector. Maybe this was an older "earlier" version?
-also there should be a Supersprint logo engraving present. To my knowledge, all their products have this. Ex (SS Stepped V1):
-You likely will also see lines/impressions in the metal from their mandrel bending machine...but likely this is not unique to Supersprint and can be found on other headers perhaps (depending on what was used to bend the pipes).
-The actual collector, and sensor bungs also look different to me (especially the EGT bung location), as do the welds for those items. Ex:


This is more typical of what Supersprint headers look like after they have been heat cycled (not the ceramic coated ones also pictured):



The only thing that reminds me of Supersprint is the serial number plate (which I think corresponds to the jig used).
For ex (SSV1):



The actual primary piping looks consistent with the Non-stepped Supersprint headers (keeping in mind that this a very highly copied design):
Ex (Non-stepped V1): http://www.m3forum.net/m3forum/showthread.php?t=466317
*also note that while these look nearly the same, the sensor bungs are slightly different as is the serial number is also different.

http://www.m3forum.net/m3forum/showthread.php?t=542230

I'd say that these are either an older set of Supersprint Non-Stepped headers or a copy. The serial number doesn't match up to any of the numbers I have found on other non-stepped Supersprint headers.

here is a good thread asking essentially the same question on a similar looking set of headers: http://www.m3forum.net/m3forum/showthread.php?t=465735

If it interests you, I'd call a representative of Supersprint or Supersprint directly to get a definitive answer. Supersprint non-stepped and Euro headers are far and away the most copied designs.


Thanks all, will try to get in contact with them this weekend.

Yea, supersprint headers have gone through a lot of evolutions. I can say for a fact that my v2 non stepped headers to not have a horse or supersprint logo on them. I am not sure if they have the number plate either. I do remember being on the phone with super sprint and sending photos to verify the headers in order to get confirmation that they were real. This was back in 2008 before the stepped headers and when all the replicas were coming to market. I do remember distinctly that some of the older NON stepped headers had a number plate on them some did not.

Now and days all headers are basically copies of those headers so in the end it's all the same unless you need the supersprint name.

Also reading the one post, I remember that exactly what the number plate is. It corresponds with the jig used. This was what I was told when talking to supersprint. It's coming back to me. Damn this was ages ago I feel. Also the line impressions were how they figured out mine were real. Those impressions were from the jig.
